1 Claim.- (c1.1's3

This invention relates generally to the handling of;money andparticularly to a coin vvending machine. 7 v v 3 1..

The main object of th' invention is to'produce a machine whereby coinsmay be vended or change given in exchange for coins of a'largerdenomination.

The second object is to produce a machine of the class described whichwill be easy to manufacture and maintain and positive in its operation.3

The third object is to construct a machine in the class described in amanner whichlends itself to inexpensive manufacture and inawhich isprovided an improved ejector mechanism.

The fourth object is to provide a means for preventing the payment ofany coins unless there are enough coins in the stack to make acompletepayment.

I accomplish these and other objects in a manner set forth in thefollowing specification'as illustrated in the accompanying drawingQ inwhich Fig. 1 is a perspective view of the complete machine.

Fig. 2 is a vertical section taken along the 22 in Fig. 3. v 2''.

Fig. 3 is a horizontal section taken along the line 3-3 in Fig. 2. 1

Fig. 4 is a fragmentary horizontal section of the ejector mechanismshowing the position of [rest Fig. 5 is a view similar to Fig. 4 butshowing a group of coins being ejected. 'f

Fig. 6 is a fragmentary vertical section along the line 66 in Fig. 4.

Fig. 7 is a fragmentary vertical sectionta-ken along the line 1-1 inFig. 4.

Fig. 8 is a view similar to Fig. 7 but showing the position of the partswith the coins partially ejected.

Similar numbers refer to the same or similar parts throughout theseveral views.

Referring in detail to the drawing, there is shown a base It) having aledge I l formed around the upper edge 12 thereof.

' the free exit of coins 20 acrossthe floor Disposed along the top edgel5 of the base I!) faces 23 and 24 conform to the shape and size of thecoins 20. The edges 25 and 26 of the members 2| and 22 are parallel andspaced to permit and over the edge ,19. v

The ends 21 3.115128 of themembers flan .2;? are spaced to permit theentrance of the arcuate ejector 29 whose up turned end 36 almost equalsin heighth the stack of coins elected at one operation.

The ejector 29 has a straight portion 3| which stops against thestraight face 32 of the member 22. The ejector 29 is mounted on thepivot 33 while the end 34 is provided with a pin 35 on which is mountedthe lever 36 on one end of which is disposed the gate 31 which normallyprevents the escape of coins 20 as shown in Fig. 4. On the lever 36 isformed a tubular end 38 into which projects the ball 39 formed on thelower end 40 of the bell crank lever, while the pivot 42 is supported bythe standards 43. A spring 44 is mounted on the bushing 45 which spacesthe bell crank lever 4| between the standards 43. One end of the spring44 engages the under side of the line 4| to urge it upward while theother end of spring 44 engages the stud 46 which is mounted on the floorplate 16. Spaced from the floor plate I6 is a plate 41, between whichand the floor plate I6, the ejector 29 can freely pass, at a levelbetween the top and the bottom of the fifth coin 20-0.

The under side 48 of the plate 41 is above the top of the fifth coin20c. The plate 41 is provided with an aperture 49, above which andregistering therewith, is a tube 50 forming the holder for the coinswhose upper end 5! is flared out somewhat as shown to receive thefunnel-shaped opening 52 of the top 53 disposed by the upper end of thecasing 54 which extends downwardly to the ledge II. The casing 54 isprovided with a pair of slots 55 which receive the outwardly projectinglevers 4'l on which are formed the key 56.

It can be seen that if a quantity of coins are placed in the tubes 5!]and the parts are in the position shown in Figs. 4 and 6, that is withthe coins 29 resting on the floor plate I 6, that the depression of akey 56 will actuate the lever 4! and move the ejector 29 to the positionshown in Fig. 5 causing the group of coins to be moved, as shown in Fig.8, out past the edge l9 into the chute B. As illustrated, the depressionof one key 56 will eject five nickels and the depression of both keys 56eject ten nickels.

In order to prevent a short change operation which might occur if therewere less than five nickels within the tube 59, I find it desirable toprovide a slug 5! which is placed on the top of the tube 50 so that whenany group of coins descend upon the floor plate It the machine cannot beoperated at least at the key where the stack 0 nickels is short.

I am aware that numerous vending and dispensing machines have beenconstructed in the past. It is, therefor, not my intention to cover suchdevices broadly, but I do intend to cover all such forms andmodifications thereof as fall fairly within the attempted claim.

I claim:

A mechanism of the class described consisting of a straight ejectorlever having a pivot point between the ends thereof and having anarcuate elector at one end whose center of. curvature is the pivot pointthereof, and having agate lever pivotly mounted between its ends to. the"end of a:

said ejector lever opposite its ejector in a manner that one end of thegate lever is juxtaposed to'the" a floor plate supporting said ejectorhaving a coin tube disposed to position coins in the path of movement ofsaid ejector and spaced from said floor plate, side walls under saidcoin tube having an opening between same for the ejection or coins saidone end of the gate lever normally closing said opening, and an oppositeopening for the passage of the ejector, said floor plate being cut awayoutside of the portion which supports the coins, the end of said gatelever in the path of said coins constituting means for preventing I theescape of coins from between said walls when no ejection is being made.
